The invention relates to bumpersfor automobiles, and more particularly to the' general -type of bumper comprising parallel upper and lower impact bars, and a rear or auxiliaryVv bar having its ends connected to the -irst-mentioned bars. j Y

The general object of the invention is to provide a bumper' of this character Vwhich is simple in Construction and economical of production and one which will be adaptedr for all of the ordinary incidents ot use.' A

:further object of the invention is to provide a bumper of this character with extensions,

in the nature of attachments, for theprotection ot' fenders.

Further andv more limited objects of the invention will appear' hereinafter and will be realized by the construction shown in the drawings wherein Fig. l represents a plan view of a bumper constructed in accordance with my invention, showing the supporting arms therefor; Fig. 2,'a detail in plan, and Fig. 3 a detail in elevation, of one of the ends-,oithe said bumper. l

`For convenience l.of description," the bumper will be assumed to be ,applied to they front end of an automobile and the terms front and rear will be used to designate the relative locations of .the parts ot the,`

bumper, but without limiting` theuse orn the latterrto either end of the automobile.

Describing the'variousV parts byA reference characters, l denotes a pair'of arms which .are adapted to be secured t-o the side mem-V bers olfl an automobile, the said arms beingA connected at theirouter ends, each by a clamp 2, with the rear or auxiliary bar oi' the bumper, which will now be described.

3, 3 denotes the upper and lower impact bars of the bumper. These bars Aare convex forwardly and are shown as spaced apart less than the width of the stock of which they are composed. The rear or auxiliary bar comprises transversely extending Venol portions 4 and a central V-shaped portion 5 which is projected toward and bears Y against the rear faces of the central port-ions of the bars 3, this engagement ot the bars 5 and 3 being due to the fact that the former bar is wider than the space between the two latter bars. The center oi' the rear or auxiliary bar is connected to the center of the bars 3 by a clamping plate 6 and bolts 7 securing the said plate tothe front bars.v

The bumper thus formed is simple and ing also secured .to the rear or auxiliarybars.

Each shortbar,comprisesan inner portion 8 which is adapted to be secured to the outer portion 4l Vof the rear lor auxiliary bar, by means ot a clamping plate 9 and bolts l() extending through the ends of said plate andy the parts 8 of the extension bars. he extension-bars 8 are so shaped at their outer portions as to bear against-:the rear faces .ot lthe outer portions or' the bars 3 and tovpro- Vject outwardly and rearwardly therefrom,

the bearing parts beingA indicated at 38 and the curved extensions being indicated at 8. The extreme ends of the rear or auxiliary bar are deilected; rearwardly, as indicated at 4,, to .provide a space between such portions and the adjacent portionsS.a ot the extension bars for the reception oi' clamping plates ll. The ends of the bars 3 and the .parts la vand 8a are connected by bolts l2 extending through the ends of the plates l1 and through the parts 8a and by center bolts 13 securing the outer end of each rear or au'xil K iary bar to the said plate ll.
